Winterizing Your Austin Pool: Lessons from the “February Freeze”
Before 2021, many homeowners in Cedar Park, Round Rock, and Pflugerville didn’t worry much about freezing temperatures. Today, we know that a single hard freeze can cause upwards of $5,000 to $10,000 in damage to pumps and heaters. At Above & Beyond Pool Service, we specialize in “Peace of Mind” winterization for the Central Texas climate. Here is the definitive guide to protecting your equipment pad.
The Physics of Freeze Damage
Why do pool pipes burst? When water turns to ice, it expands by approximately 10%. In a closed PVC pipe or a cast-iron heater manifold, that expansion has nowhere to go. The resulting pressure acts like a slow-motion explosion, cracking even the strongest materials. Moving water is much harder to freeze than stagnant water, which is why your pumps must run 24/7 during a freeze event. Most modern automation systems have a built-in freeze protection mode, but it is your responsibility to ensure it is functioning correctly. If your system fails to start, you may need a repair diagnostic.
Emergency Gravity Drain Protocol (Power Outage)
If the grid fails during a freeze, your automation cannot save you. You must act within the first few hours:
- Kill the Power: Turn off the breakers at the equipment pad to prevent dry-starting.
- Remove Drain Plugs: Every pump, filter, and heater has small drain plugs. Remove these to let the water out.
- Open Air Relief: Open the air relief valve on top of your filter to allow the water to drain via gravity.
- The “Bucket Trick”: Place all your drain plugs in the pump basket so you don’t lose them!
Protecting Your Heater and Filter
Heaters are the most fragile and expensive part of your system. They contain thin copper tubing that can crack instantly if water is left inside. Draining the heater is your absolute priority during a power outage. Similarly, if water freezes inside your filter tank, it can crack the shell. We specialize in “pad-side” equipment installations for homeowners who need to replace damaged units after a freeze. Don’t wait until the next “Big Freeze” to realize your equipment is at risk.
